The first discharging mechanism 1 and the second discharging mechanism 2 are both provided with a central shaft for placing roll paper, and the paper core of the roll paper is sleeved on the central shaft.
The paper tape 100 to be conveyed on the second discharging mechanism 2 sequentially passes through the third press roller mechanism 5, the fourth press roller mechanism 6, the paper cutting and sticking mechanism 8 and the pressing mechanism 9. The pressing mechanism 9 is used for clamping a paper head of a paper tape 100 to be conveyed, and the paper tape 100 passes through the third pressing roller mechanism 5 and the fourth pressing roller mechanism 6 to be tensioned according to an S-shaped path, so that the paper tape 100 is always tensioned from the second discharging mechanism 2 to the third pressing roller mechanism 5 and the fourth pressing roller mechanism 6.
